Thranduil is a fictional character in J. R. R. Tolkien's Middle-earth legendarium. He first appears as a supporting character in The Hobbit, where he is simply known as the Elvenking, the ruler of the Elves who lived in the woodland realm of Mirkwood. The character is properly named in Tolkien's The Lord of the Rings, and appears briefly in The Silmarillion and Unfinished Tales.

Bard the Bowman is a character in J. R. R. Tolkien's The Hobbit. A Man of Laketown and a descendant of the ancient Lords of Dale, Bard manages to kill Smaug, the dragon, after which he becomes king of Dale. Tolkien created the character specifically to kill Smaug, since none of the other protagonists of the story were able to fulfill this role. Bard the Bowman may have been inspired by the warrior Wiglaf in the Old English poem Beowulf.
